Which metals react slowly with cold water but vigorously with steam?
All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).
Which metals act violentely with water?
The Alkali metals (group 1) and the Alkali Earth metals (group 2) react violently with water. Lithium and magnesium show slow reactions in boiling water. Sodium and potassium reacts violently with flames with cool water. The elements in higher periods (strontium, barium etc.) react explosively.Elements in the 1st group react rapidly with cold water. The rate of reaction increases down the period. The elements in the 2nd group also reacts with hot water or steam.
What happens when francium and cesium are exposed to water?
All alkali metals react violently with water forming a hydroxide and hydrogen.
Which two metals explode in water?
Group 2 metals (alkaline earth metals), calcium and barium would be examples
How alum dissolves in the water?
Aluminum can not be dissolved in water, because it is a metal from group 13. Only some of the earth alkaline metals and all of the alkaline metals dissolve (and react!) with water.
When metals react with water for class 8?
Very reactive metals - from group 1 and 2 of the periodic table - can react with water.
Which metals react slowly with cold water but vigorously with steam?
All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).
Why is group 1 metals called alkali metals?
They're metals that form alkaline compounds when they react with water.
How do non metals react with water?
Most of them do NOT react with water. Only fluorine and to some extend chlorine do. Actually the only good 'water reacting' group of elements is group 1: the alkali metals.
Why are group 1 metals knowns as alkali metals?
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
Do metals in group 1 react more with water than in acid?
yes
What happens when metal reacts with metal?
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.

What happens if metals react with water?
In the case of rust anyway, metal oxides form
Which group on the periodic table contain metals that react vigorously to water?
Alkali Earth metals are the most reactive metals on the periodic table.
Do non metals react with water?
Most of them do NOT react with water. Only fluorine and to some extend chlorine do. Actually the only good 'water reacting' group of elements is group 1: the alkali metals.
Which metals does not react with water?
Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.
